LED comparrison
I know that Candlepower is outdated but could you tell me how much THIS lights up inside a camper compared to an 1157? Thanks

They put out as much light as a $1.99 25SMD panel but the light is bluer.
You probably got "bright white" or "cool white" color temperature.
Yes, that 2835 board is odd. I used to think that there was 5050 at 14 lumen/watt, 1210 at 7 L/W, and 3528 being the same as 1210. I guess, it's never late to learn.
Back to the OP: it is close to 18W incandescent, not 20W. Old 18W is approximately 290 lumens. Color temperature for that LED is a big unknown. When they don't specify, it's - usually - warm white, a color close to incandescent, but there is no way to tell.
Here is some from Ebay. No regulator, so there is no radio noise. If you click on the "Visit Store", and then dial in search 1156 or 24-5050, or 48-1210, you'll get more, and in 10Xpacks, and in cob shape or round boards.
Equivalent brightness to 20W incandescent is 24 diodes of 5050 size each, or 48*1210. Also, watch lumens - some boards can be high-current, and then they more lumens with the same number of diodes. But mostly it's 24-5050.
Also, watch color temperature. When this seller says not "warm white" but "white", it's a wrong term because he really means "cool white" 7000K, which is cooler/bluer than incandescent 3500K. There should be just "white" around 5000 between warm and cool, but they don't have it.
No affiliations, Tom - 2 post above - and some other members bought from there, but there are many others sources too. No need to remind of slow boat from China - could be few weeks, a month, or longer.
